Bulletin

Solar activity was very low with X-ray flux remaining below B level and no spots on the visible disk. This is expected to remain so over the next days.

No Earth directed CMEs have been recorded in coronagraph images.

Proton flux levels were at background values and are expected to remain so.

Solar wind conditions were near nominal. Solar wind speed was between 370 and 410 km/s. Total magnetic field saw a jump to 6-8nT just before midnight and remained around 6nT since. Bz was variable and the magnetic field phi angle was in the positive sector. Solar conditions are expected to remain near nominal over the next days.

Geomagnetic conditions were quiet to unsettled (NOAA Kp and local K Dourbes 0-3). Generally, quiet conditions are expected over the next days with occasional unsettled conditions possible.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 23 Stationen.
